5 cm cube = 125 cubic cm = 125 millilitres.
There are approximately 30 cm in each foot, so 125 cm would be 4.17 feet.
Almost anything you like. 125 cm * 250 cm * 100 cm of vacuum (or interstellar material) and the mass is near enough 0. On the other hand, 125 cm * 250 cm * 100 cm of a neutron star will have a mass of many many tons. So pick your substance and you will get almost any mass you like.
